Description

The self-enclosed agitator truck of horizontal

Technical field

The structural principle that self-closed stirs under a kind of horizontally disposed tank body rotary state is the utility model is related to, particularly It is related to a kind of mixing transportation of engineering machinery field.

Background technology

Concrete mixing and transporting car is made up of automobile chassis and concrete stirring special purpose device, and early stage is Germany and day This proprietary technology, it is tilting rotating device.The product of present Chinese trucd mixer manufacturer has the technical characterstic of oneself, But researched and developed in the design basis of both tanks.Its special mechanism mainly include drive system, underframe support, tank body, Charging/discharging device, operating mechanism, purging system etc..Operation principle is to be driven the power output of automobile chassis by power takeoff The variable pump of hydraulic system, mechanical energy is converted into hydraulic energy and is transmitted to fixed displacement motor, motor drives reductor again, is driven by reductor Dynamic agitating device, is ceaselessly rotated by tank body internal helical blades, material in tank is kept its uniformity, and in discharging Material operating is driven to complete discharge process.

Concrete mixer currently used in the market is centrum shuttle-type tilting device, mixing drum high inclination-angle（10°-20 °）Design, efficient loading capacity are 60%, and tank body will surround tank body axis rotation when vehicle is run, and drive concrete upset, its is heavy The heart deviates whole vehicle center 50~100mm of line towards mixing drum rotation direction, roll force produced by having the lateral inertia force of increase Adverse effect；The weight of tank body and its delivery material is shared by reductor and support roller, and reductor is effectively fixed, is connected to tank Raceway on body is to be placed on tugboat, by support roller support raceway rotation.Because upper and lower abrupt slope, tilted road surface and hollow jolt The complex characteristics of the building site such as road surface road conditions, it will bear tank body and delivery weight of material and the inertia impact from all directions Power, the support that tank body departs from roller is limited, to reduce the damage to reductor and tank body and the impact to support roller, unique side Method is to set raceway band in raceway outer, and both ends are fixed by bolt connection sub frame, prevents tank body from departing from and beating, but according to Tank body is not resisted so and its delivers inertia impact huge during weight of material motion, especially because emergency brake vehicle loading Inertia impact caused by fluid, all act on tank body and turn to be added on reductor, if Vehicular turn slightly tilts, after tank body Portion will be disengaged from support roller, can not effectively be fixed for tank body rear portion and share the potential safety hazard of inertia impact and can clap very much.

Because tank body rear portion can not effectively be fixed, tank body bob and the strength to swing are very big, are held by reductor The weight received and rocking from all directions, the damage to reductor are very big, and the output flange of reductor must be at+6 ° In the range of deflection could compensating tank body axis displacement, ensure the driving not torsional deformation in by vehicle traveling process of tank body Influence.Due to technical bottleneck, domestic reductor holds the working environment that can't stand so great destructive power, the deceleration of present trucd mixer For machine all by imported equipments and parts, price is several times of domestic reductor.

Because guide Taper Pipe leads directly to the design of chamber opened type, frequent material leakage, concrete material, pollution road surface are wasted, in order to meet to fill Carrying needs, and improves fluid level, it is necessary to material guide port bottom is designed higher than into carry fluid liquid level, and also examined Consider influence of the gradient for liquid level, in order to avoid fluid overflows, so that vehicle highly improves, center of gravity improves；

If improving vehicle carrying capacity, length of tank certainly will be increased（Vehicle width has the limitation of vehicle gabarit can not More than 2500mm）, such total height accordingly increases, and is both not suitable for road conditions environment, met vehicle run stability and security again, Also vehicle profile height limits simultaneously.If by reducing the method for material guide port, to control vehicle, highly fluid level is corresponding Reduce, idle space increase.Therefore length of tank and design height influence each other and mutually restricted, and to accomplish that large-tonnage stirs Haulage vehicle, tilting tank body are difficult to realize.
